? Well all good points. Yes it's in the wood surrounding the bushing but on extreme cases it seems to have crept into the wood. ? Here's the deal I have two sets of 20's wippens that are absolutely free of verdigris. & third that is not. SO if the gunk is in the flange only then new flanges would solve the problem.?? Maybe they didn't get the gunk. They are well preserved? & frictions & pinning are excellent. ? As you say this would be in rare situations such as an econo job, ?not something I would usually subscribe to but I hate wasting what seems like salvageable technology when feasible. Thanks for the feedback ? ?? Dale ? It's a reasonable idea that might make sense in rare situations--though I'm not sure what those would be--, but in general, not worth the effort and too many potential liabilities. At least that's my view. If you're not sentimental about original designs, there's certainly no reason to get sentimental about original wippens with verdigris.

We started brainstorming how we could solve this given the contamination is in the wood.? Now I know many of us have re-pinned & re- bushed ...put on new flanges?etc. & in the end all for nothing as it returns, But with a good set of wippens approaching 1000 bucks the idea has my attention. ??I told my Dad I was thinking about how to cut out the birds eye & then machine a new insert with birds eye & all. My thought was that if the new insert was put in with epoxy that this would act as a verdigris barrier from entering back into the new wood. Then My Pops says "why not just coat the existing birds eye with epoxy & slide a coated pin thru the hole to seal up the exposed inner wood which should prove de a barrier to any further contamination". Then pin on new flanges.?I thought the idea had merit. ? I mean for a few short hours of pinning & coating?an original set of beautifully made & machined? maple wippens could be preserved & re-used at any level of performance required.? ? How bout some discussion. ? Dale ? -------------- next part -------------- An HTML attachment was scrubbed...
